WHY WILL ACRYLIC APPEAR CRACK AFTER SILKSCREEN?
Why there are a lot of small cracks
appeared after acrylic with silk screen a period of time, it will not effect
the appearance but also feel not good.
There are several factors for the cracks,
first is the bad material, the another is ink’s quality. If because of the bad
material, we can find a piece we did silk screen before the remaining leftover
crack, to judge, using the same ink, if will not appear crack, we can confirm
that the material is no t good. Maybe with too much water, you can try the
acrylic sheet baking temperature 60 degrees 30 minutes in the screen printing.
If still with crack, it must because of the
ink. Because acrylic effected by solvent corrosion, will cause the cracking
phenomenon.so if the use of ink is not applicable, such as toluene, solvent
ink, may make the acrylic sheet cracks after screen printing. The crack can be
used when no problems before printing ink (different color silk screen printing
ink), whether the problem quickly, reduce the time and avoid the waste of
materials.
In addition to, as plate electrostatic
dust, in the screen printing or fill in the paint before the use of suede with
soap and water or 1% soft cloth to wipe clean, in order to achieve the cleaning
effect. It is very important to acrylic board printing, select the kind of
quality is better, especially for the display
stand products, acrylic products, the appearance of transparency
requirements are very high. The ink is relatively better, and ink quality
directly affect the appearance.
